This is a repair service for the ABS module commonly found in Mercedes-Benz models, which may be suffering from:

• Loss of wheel speed sensor signal (intermittent or permanent)

Our service includes a full diagnostic, internal inspection, and component-level repair. We thoroughly test the repaired module on our in-house bench test rig to confirm correct operation before dispatch.

Important: The most commonly reported fault is the loss of wheel speed signal, even when the wheel sensors and wiring are confirmed good.
